/** \brief
* Processes a limitfile= option, parses and applies the limitfile to compilation control.
*
* A limitfile is a compiler verbose log, produced by the option -Xjit:verbose,vlog=filename
* When a verbose log is used as a limitfile, only the methods contained within the file
* will be compiled if they are queued for compilation. The format of the method entries in
* the file must match that of a verbose log.
*
* The option can be used in 2 ways:
* limitfile=filename
* limitfile=(filename,xx,yy)
*
* The when the latter is used, xx-yy denotes a line number range (starting at zero and ignoring # comments)
* to restrict the limiting to. This is commonly used in debugging to narrow down a problem to a specific
* method by doing a binary search on the limitfile.
*
* \param option
* Points to the first char after inlinefile=
*
* \param base
* Unused variable needed for downstream projects.
*
* \param entry
* The option table entry for this option.
*
* \param cmdLineOptions
* The command line options.
*
* \param loadLimit
* The load limit.
*
* \param pseudoRandomListHeadPtr
* A list of pseudo random numbers.
*
* \return
* The unmodified parameter option if there is a problem with the file, aborting JIT initialization.
* Otherwise a pointer to the next comma or NULL.
